IMPROVEMENT IN GlMLET-HANDLES.

Specification forming part of Letters Patent No. 143,142, datedSeptember 23, 1873 application filed June 28, 1873.

[[0 all whom it may concern.-

Be it known that I, OHARLEs L. GRIsWoLD, of Chester, in the county ofMiddlesex and State of Massachusetts, have invented a new and valuableImprovement in Gimlet-Handles; and I do hereby declare that thefollowing is a full, clear, and exact description of the constructionand operation of the same, reference being had to the annexed drawingsmaking a part of this specification, and to the letters and figures ofreference marked thereon.-

Figure 1 of the drawings is a representation of a cross-section of mygimlet-handle. Fig. 2 is a longitudinal section of the same. Fig. 3 is aview of a gimlet. Figs. 4 and 5 are, respectively, views of the separatehalves of my gimlet-handle.

This invention has relation to gimlets, screwdrivers, and other smalltools which are operated by rotary movement; and it consists in theconstruction and novel arrangement of the hook at the end of the shankand the transverse male and female screw forming the handle.

The object of this invention is to provide a handle which can be packedin small compass and readily applied to a variety of tools of thecharacter mentioned, the shanks of said tools having been suitablyfashioned in the hook form.

In the accompanying drawings, the letter a designates the shank of thetool, the end of which is bent to form a hook, as shown at b. 0indicates the handle. This consists of the sections 01 and c, the formerof which is provided with the screw-stem z, connected to the handleportion by the enlargement a, which is designed to fit the span of thehook I) of the shank a.- The section e is perforated and threadedinternally to receive the screw-stem z of the section 11. Both sectionsare provided with the shoulders or faces o, designed to engage with thesides of the hook b and hold the same firmly in place when the saidsections are screwed together. i

The opening of the hook between its end and the shoulder of the shankwhere the bend commences is designed to be less than the diameter of theenlargement to ordinarily, and greater than the diameter of thescrew-stem z. This is to enable the hook to be slipped on its seatwithout disconnecting the sections, and, when located thereon, toprevent its displacement without separating the sections sufficientlyfor the purpose.

WhatI claim as new, and desire to secure Witnesses:

SAMUEL A. WEIGHT, HENRY W. CHURCHILL.
